A lftorney Patented June 3, 1930 mass? 1 GEORGE E. BENNETT; on POTEAU, OKLAHOMA TRANSMISSION Application filed December 7, 1929. Serial No. 412,531.

This invention relates to transmissions and more particularly to devices of this characterwhich dispense with the use of gears such as are commonly used for transmitting power from one shaft" to'another.

An important feature of the invention resides in the provision of a rotatable cam disc or'plate which c-o-acts with an oscillating bar mounted in a suitable casing which bar is operatively connected to a crank shaft in a manner to rotate the latter when the bar is oscillated by the cam disc.

Other objects of the invention are to provide, in a manner as hereinafter set forth, a transmission of the aforementioned character which will be simple in construction, positive and silent in operation, strong, durable, and which may be manufactured at low cost.

The foregoingandfother objects and advantages of the invention will be come apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein z- Figure l is a longitudinal vertical sectional view of a transmission constructed in accordance with this invention.

Figure 2 is a vertical cross sectional View taken substantially at right angles to Figure 1.

Figure 3 is a horizontal sectional view taken substantially on the line 33 of Figure 1 and looking in the direction of the arrows.

Figure 4 is a detail view in top plan, partly in section, showing the oscillating rod which is actuated by the cam disc.

Referring to the drawings in detail, the reference character 1 designates a casing including the convex side walls or body portion 2, a dome 3 on the upper end thereof in communication therewith, said dome being open at its top and provided with a removable closure plate 4 which is secured in place through the medium of the bolts or screws 5.

The lower end of the casing includes a fiat bottom wall 6 provided with the centrally disposed opening 7 through which extends the rotatable drive shaft 8 from a suitable source power. A cam disc 9 is fixed on the inner the bar 14: to

end of theshaft 8, as clearly seen in Figure 1 of the drawings. An internally threaded flange 10 extends downwardly from thebot tom wall 6 of the casing concentrically with I respect to the opening 7 and shaft Sandcon 55 stitutes a support or a thrust bearing 11 of any suitable construction. Y 1

On diametrically opposite sides, the body portion 2 of the casing 1 is provided with in} wardly converging pairs of verticallydis posed ribs or flanges 12 which provide dovetail channels 13. v v p I An elongated bar 14; extends transversely over the upper face of the cam disc9and is -prov1ded','ad acent its opposite ends, -withl 6 pockets ordepressions 15 for the reception of, the anti-fricti0n balls 16 which are adapted to travel over the upper face of said cam shaft. On its opposite end, the bar li is pro vided with the cap 17 having the longitudinally extending trunnions 18 which project into the channels 18 of thecasing land have V mounted thereon the tapered anti-friction rollers '19 whichare enclosed in thecages 20, the cages 20 are ofa size and configuration: to fit slidably. between the ribs or flanges in a manner to permit the adjacent endof.

I move in- 'a .vertical plane, said f ribs or fianges'constituting guides for the op- I posite end of said bar, as will be apparent The upper side of the bar lt is provided with longitudinally spaced depressions 21: for the reception of the ball heads 22 on theflower ends of the connecting rods 23. The-,cdnniect-Q ing rods 23 are coupled to the bar 14 through 8 the medium of the detachable annular plate or ring. 24 which encircles the ball heads =22 and maintain thesame in the depressions 21 of the bar. A crank shaft 25is journal'ed I in the dome portion 3 of the casing, as at 26. The portion of the crank shaft within the dome 3 is provided with'a pair of oppositely extending cranks 27and28 to which the "up- 'per ends ;of the connecting rods 23' are con-" nected through the medium of :universal" joints 29. A central main bearing3O in'the form of a universal'jointmay be previded for 1 the. crank shaft between the crank portions 27" and 28 and said main hearing may be
